JBL TUNE-130NC-TWS user manual

There can be a few reasons why one of your JBL Tune 130NC TWS headphones may not be connecting:
1. Bluetooth Pairing: Make sure both the headphones are in pairing mode and that your device's Bluetooth is also enabled and searching for devices. Sometimes, one earbud may fail to connect if it is not in pairing mode.
2. Battery Level: Check the battery level on both headphones. If one earbud has a significantly lower battery level, it may fail to connect or disconnect frequently. Ensure that both earbuds are charged properly before attempting to connect.
3. Resetting Headphones: Try resetting the headphones by turning them off, resetting your device's Bluetooth settings, and then restarting the pairing process. Additionally, try resetting the earbuds by placing them in the case, closing the lid, and then opening it after a few seconds. This can help to resolve any connectivity issues.
4. Firmware Update: Check if there is a firmware update available for your JBL headphones. Sometimes, firmware updates can fix connectivity issues or improve the overall performance of the earbuds. Make sure to update the firmware if required.
5. Interference: Ensure that there are no other Bluetooth devices or Wi-Fi routers interfering with the connection. Move away from any potential sources of interference or try connecting the headphones in a different location.
If none of these steps work, contacting JBL customer support or referring to the user manual can provide further assistance in troubleshooting the issue.
